The STM32F401xB/STM32F401xC device family is based on the high-performance ARM Cortex-M4 32-bit RISC core operating at a frequency of up to 84 MHz. Its Cortex-M4 with FPU core features a Floating point unit (FPU) single precision which supports all ARM single-precision data-processing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU) which enhances application security.STM32F401xB/STM32F401xC devices incorporate high-speed embedded memories (Flash memory up to 256 Kbytes, up to 64 Kbytes of SRAM) and an extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB buses and a 32-bit multi-AHB bus matrix.All devices offer one 12-bit ADC, a low-power RTC, six general-purpose 16-bit timers including one PWM timer for motor control, two general-purpose 32-bit timers. They also feature standard and advanced communication interfaces.Core: ARM 32-bit Cortex™-M4 CPU with FPU, Adaptive real-time accelerator (ART Accelerator™) allowing 0-wait state execution from Flash memory, frequency up to 84 MHz, memory protection unit, 105 DMIPS/1.25 DMIPS/MHz (Dhrystone 2.1), and DSP instructionsMemoriesUp to 256 Kbytes of Flash memoryUp to 64 Kbytes of SRAMClock, reset and supply management1.7 V (PDR OFF) or 1.8 V (PDR ON) to 3.6 V application supply and I/OsPOR, PDR, PVD and BOR4-to-26 MHz crystal oscillatorInternal 16 MHz factory-trimmed RC32 kHz oscillator for RTC with calibrationInternal 32 kHz RC with calibrationPower consumptionRun: 137 µA/MHz (peripheral off)Stop (Flash in Stop mode, fast wakeup time): 42 µA typ @ 25 °C; 65 µA max @25 °CStop (Flash in Deep power down mode, slow wakeup time): down to 10 µA typ@ 25 °C; 28 µA max @25 °CStandby: 2.4 µA @25 °C / 1.7 V wi
